16 Claims.

This invention relates to an improvement in dirt handling devices andmore particularly to those of the type used for scraping, hauling, andleveling.

In its preferred form, the invention comprises a device that may formpart of, or be attached to, a tractor or other heavy duty vehicle, andconsists of an adjustable loading, carrying, and emptying member locatedforwardly of the vehicle to which it is attached, being equipped withfront end wheel support. In operation, the member precedes the poweredvehicle.

Prior to this invention, dirt handling devices of this nature haveconsisted of a wheeled vehicle having a one or more element dirtcarrying scoop, and were adapted to be attached to and towed behind apowered vehicle; Devices of this nature are primarily utilized inscraping up and hauling quantities of loose dirt. They are not intendedto, and are generally incapable of dumping at exact locations, such asspecial fills over banks, etc., and, furthermore, cannot level the dirtthus hauled and dumped. This is due generally to the necessity of thepowered vehicle preceding the dirt handling device to a dumpinglocation, or, if the dumping device is capable of being backed intoposition by the powered vehicle, being provided with means for dumpingin a direction and manner opposite to that of loading. The dirt handlingdevices, applied to or located forwardly of a powered vehicle, are inthe nature of road scrapers, ditch diggers or shovels, and areindividually incapable of digging or scraping, carrying, and levelinglarge quantitles of dirt.

The present invention is intended to eliminate the heretofore necessaryuse of several types of dirt handling devices by combining certainfeatures, hereinafter described, in one device. To accomplish this, thedirt handling device is located forwardly of the powered vehicle andinoperation always precedes the vehicle. Thus the operator may keepthe'powered vehicle on firm ground, load the device, raise it, carry andempty the dirt at a given location, and, through use of the same device,level'or bank the dirt as may be required. The operator is not requiredto turn around and divert attention from the direction of travel of thepowered vehicle in the operation of the device. Furthermore, it ispossible, particularly in road filling and grading work, to dig, carry,dump, and level large quantities of dirt with greater rapidity throughthe use of a single device, whereas, in the past this work has ascraper, dirt loader and carrier, and bulldozer. One of the objects ofthe invention lies in the provision of a dirt handling device that mayform part of or be applied to the front end of a powered vehicle.

Another object of the invention lies in the provision of a dirt handlingdevice, the forward end of which is wheel supported and the rear endattached to and carried by a powered vehicle.

Another object of the invention lies in the provision of a dirt handlingdevice at the front end of a powered vehicle that is capable of loadingand carrying large quantities of dirt for considerable distances and ata speed limited only by that of the powered vehicle.

Another object of the invention lies in the provision of a dirt handlingdevice located at the front end of a powered vehicle that is capable ofcarrying, emptying, and leveling large quantities of dirt.

Another object of the invention lies in the provision of a devicelocated at the frontend of a powered vehicle that may be used forsurfacing or leveling dirt, as may be required, in the building andgrading of roads.

Other and further objects and advantages of the'invention will be morefully understood from a consideration of the following specificationtaken in conjunction with the accompanying drawings; and in which Figurel is a side elevation of a dirt handling device embodying one form ofthe invention applied to the front end of a tractor of the caterp artvpe;

Reference is nowhad to the drawings,.and particularly to Figures 1 to 6,inclusive, wherein one modification of a dirt handling device,embodying-the invention, is shown, being generally indicated by thereference numeral 10., The device comprises a 'frame ll having duplicateside members 2. These members may consist of upper and lower rails I3and I4, connected by middle and rear vertical rails 15 and It. At theirforward ends the rails 13 and I 4 are connected by a member I], thelower portion l8 of which is rearwardly offset to accommodate a wheelsup-' port for the device. The members l2 are spacedly joined by severalcross members, such as indicated at I9, 2|, and 22. At the forward endof the device, a top cross' member 23 is provided.

Y By means of a suitable shaft or pin 24, the member 231s pivotallyjoined to the member 22. The ends of the member 23 extend beyond thesides of the device and terminate in downwardly projecting portions 26.A vertical opening is. made through the portion 26, and the shaft 21 ofa fork 28 projects upwardly therethrough, beingfitted above the member23 with a lever arm 29.' The arms of the fork 28 mount an axle shaftwhich carriesa suitable wheel 3|. I The arms 29 are pivotally connectedthrough rods 32 with an arm 33 that projects upwardly into a gearhousing 34.

Extending rearwardly from the housing 34 is a steering'shaft 36. 'A wormand gear structuxein the Ehousing '34 serves to transform rotationalmovement of. shaft 36 into lateral movement of rods; 32 and arms '29 forthe purpose of steering wheels 3|. As shown inthe drawings, one-or moreuniversal joints31 may be'provided to ac-- f commodate the shaft'36 toany type of powered vehicle. The shaft is, of course, provided with asuitable steering wheel 38.

Connecting the lower rails l4, somewhat forwardly of the cross memberI3, is a shaft 33."

p This shaft is carried by the rails l3 in bushings spect to the framell.

4| and fitted with nuts 42. Between the members I2 is a scoop, generallyindicated by the numeral 43. This scoop includes side walls 44 and basewall 45. The shaft .39 projects through a suitably reinforced portion 46of the side walls '44,

adjacent the rear end of the scoop, and serves to mount said scoop forpivotal movement with re- The forward end of the base wall 45 may beformed with a scraper edge,

laterally beyond the width of the scoop and is suitable pressure sourcecommon in tractors of the type to which the invention is applicable, the

shafts simultaneously move forward, causing the rear wall 49 to moveforward, in the same posi-' tion shown in Figure 1 to a position such,for,

example, as indicated in, Figure 3, in any suitable'manner, as by meansof a'pair of small hydraulic rams 56. The cylinder of each of these ramsis pivotally mounted on the outer face of the,upper rails l3 of thedevice, and the shaft 51 thereof is joined to a lug 58, carried by theside walls 44 of the scoop. It will be understood that these rams havepositive support in all positions and, consequently, the operator of thedevice may incline the scoop 43 about its pivot to any desired extent.

The modification of the invention of the device above described isapplicable, with only slight variation, to the front end of any ofseveral types of powered vehicles. vention under consideration, it isapplied to the forward end of a tractor of endless tread type.

r to the tractor.

From the foregoing, it will be understood that the scoop 43 may bepivotally lowered, by means of rams 56, into dirt digging or scrapingposition,

such as is indicated in Figure 3 of the drawings,

, tion of the wheels 3! throughmember '23 andshaft as. In other words,the tractor may be onv level ground and the wheels 3 i .on unevenground,

and the scoop and frame ll will not be laterally strained or twisted.When the scoop has been filled with-dirt, the rams56 are again operatedto raise the forward edge 41 out of contact with the ground. The loadmay now be transported to any given point, such, for example, as theedge -of a bank, and the operator may then actuate rams 53 which willmove the rear wall 49 of the scoop forwardly, forcing the loadtherefromfat the desired location. If the dirt thusdumped is notpositioned as desired, the operator may back the vehicle, tilt thescoop, and, since the wall 43 is still positioned atthe forward endthereof, use the device as a bulldozer.

'Reference'is now had to Figures 7 toll, in-

' clusive, wherein a modification of the dirt hansubstantially as shown,that may be extended dling device, forming the subject of the invention,is shown, being generally indicated by the In the disclosure of the inofa cross member 14. The cross member 14 is located just forwardly of across support 16. Centrally of the support 16 is a guideway 11.

A block 18 is mounted in the guideway 11 and has pivotal connectionthrough a shaft 18 with the cross member 14. The upper end of the block18 is provided with a member 8i, the ends of which extend laterallybeyond said block. To

these ends are secured the ends of shafts 82, which constitute theexposed portions of pistons for hydraulic rams 83. The rams 83 may beformed in the support 16 and serve as a. variable support between thewheel support and the frame of the device. Hydraulic rams 83 have beenshownsincetractors of the type to which the invention is applicable arefrequently equipped to operate such rams. It will be understood,however, that other adjustable means may be employed.

The frame 65 rigidly mounts a scoop 84 that includes bottom and sidewalls 86 and 81. A rear wall 88 is provided for the scoop and is movablefrom the rear to the forward end thereof by means of suitable connectionwith hydraulic rams 88 that are secured, in any suitable manner, to theside members 66 of the frame 65. Wall 88 may be provided with suitableguide blocks 8| that ride in channels 82 secured to the side walls 81.

The wheels 1I may be provided with a steering mechanism generallyindicated by the numeral 84, or may be of the caster type and adapted tofreely follow the direction taken by the tractor. When it is desired touse the device, the operator of the tractor causes rams 83 to lower theframe 65 and scoop 86 from the full to the dotted line positionof Figure7. This brings the front or scraper edge of the scoop into contact withthe ground and forward movement of the tractor causes dirt to becollected by the scoop. When the scoop has been filled, the operatoractuates rams 83 to raise the frame and scoop. The load may nowbe movedtoa desired location and rams 88 actuated to move the rear wall 88 ofthe scoop forwardly to evacuate the dirt.

Reference is now had to a further modification of the invention shown inFigures 12 to 15, inclusive, of the drawings. In this instance, the dirthandling device, generally indicated by the numeral 83, is applicable toa dual wheel-drive, rear-motored vehicle 88. As is mommon practice indual wheel-drive vehicles for use with dirt handling devices, a pair offront wheels are necessary to maintain proper balance, and since thedual wheels are not separately powered, as is the case with caterpillartractors, the front wheels are utilized to steer the vehicle. Underthese circumstances, the device 83 may be made an integral part of thevehicle 84. Upper and lower side members 86 and 81 extend forwardly ofthe forward vehicle wheels 88 and are laterally outwardly curved, beingjoined to or made integral with the side members 88 of the device. Theside members 88 include lower rails IN, to the rear ends of which ascoop I82 is pivotally secured. The scoop includes bottom rear positionof the motor of the vehicle.

and side walls I83 and I84. An adjustable rear wall I86 is provided forthe scoop, being capable of movement throughout the scoops lengththrough connection with rods I81 of hydraulic rams I88. By means ofbrackets I88, rams I88 are pivotally joined at their forward ends to therails 81 of the vehicle in order that rods I81 may, at all times, movein a direction parallel with the scoop I82, whether it be in thecarrying or digging and scrapingposition. Suitable guideways III may beprovided in the side walls of the scoop to receive blocks I I2 that arejoined to the upper comers of the wall I86. The forward ends of the sidemembers 88 are connected by a substantial cross member II3 that ispivotally connected, through a shaft H4, with a cross brace II6. In thepresent disclosure this connection may be had through an element; II1that extends over the cross members II 3 and ter= minates in adownwardly extending portion II8. Thus, the shaft Ill projects throughthe portion I I8 and the brace I I6, and pivotally positions the crossmember 3 therebetween. Any suitable steering mechanism, such asheretofore described in connection with the other modifications of theinvention, may be provided by which to turn wheels II8. These wheels aremounted in forks I2I that depend from the ends of the cross member II3.

In this last described modification of the invention any heavy loadcarried by the scoop I82 is, to some extent, counter-balanced by the Thetype of vehicle to which this modification is applicable is more mobilethan a vehicle of the caterpillar tractor type and, consequently, thedevice may not only load itself, but rapidlytransport a load over aconsiderable distance and empty and position the load thus deposited.The scoop I82 is moved from the position of Figure 12 to that of Figure14, in any suitable manner, as by a pair of hydraulic rams I22. Theserams may be positioned substantially as the rains 56 shown in themodification of Figure 1 of the drawings.

A still further modification of the invention, as applied to or formingthe forward end of a powered vehicle, is shown in Figures 16 and 17,

to which attention is now directed. In this modification, the frame of apowered vehicle I23 extends forwardly of the driving wheels I24 and isattached to or made integral with a frame I25 that includes upper andlower side rails I26 and I21. Suitable vertical rails I28 and I28connect the upper and lower rails. As shown in the drawings, the upperrail, rearwardly of the device, is integral with an upper rail of thevehicle frame I23. The rails I26 and I21, on each'side of the device,converge vertically to form a forward wheel-mount I38. These rails alsoconverge inwardly from the sides, as may be clearly seen in .Figure 17.A suitable housing I3I is carried by, or may form part of the convergingends of the upper and lower rails I26 and I21. A member I32 abuts thelower end of the housing I3I and includes a shaft I 33 projectingupwardly through said housing. The support I 32 is connected through apivot member I38 with an axle housing I35 through which a suitable shaftprojects to mount wheels I36. The upper end of shaft I33 is fitted withan arm I31, to the free end of which suitable steering mechanism (notshown) may be attached. .Due to the pivotal connection of the supportI32 with the axle housing I35, the wheels I36 are capabl of adjustingthemselves, during use of the device, to uneven ground without cantingor iniany way twisting the frame I25 'with respect to the vehicle ofwhich it forms a part.

The rear wall I45 of the scoopis movable forwardly to the front edge to evacuate a load of dirt, and,for this purpose, is connected with hydraulic rams I46. As in themodification shown in Figure 12, the rams are provided, at theirforwardends, with brackets lfl that. are joined through pivots I48 tothe frameI23 of the vehicle.

The modification just described further increases the possible uses ofthe present invention in the handling of quantities of dirt, inasmuch asthe scoop I39, with the wall I45 moved to the forward end thereof, mayserve as a road surface scraper and. following suchwork, the wall I45may be returned to the rear of the scoop and the surface materialpreviously scraped gathered up in the scoop and conveyed to any desiredlocation and evacuated. Following this, the device may be used as abulldozer to position or level the dirt thus moved.

Applicant has shown and described several} modifications of theinvention, but it will be apparent that in each modification the dirthandling device is located forwardly of the vehicle to which it isattached, or of which it forms an integral part, and by reason of thisposition, as well as the adjustability of the scoop and the rear wallthereof, the invention is capable of per-,

forming several types of work required in build- 1 ing and gradingroads, as well as other work that was formerly accomplished through theuse,

of two or more devices, either alternately attached to the same poweredvehicle, or attached to separate powered vehicles. In other words, the

invention proposes to eliminate the present ne-I cessity of a poweredvehicle for each piece of handling equipment by making possible the usequirements.
